Yandex offers a powerful solution to this problem that can be integrated directly into the operating system Android. Connecting the service does not require deep technical knowledge, however, for maximum efficiency it is necessary to correctly configure access rights and filtering parameters.
In this article we will analyze in detail the installation and configuration process call blocker. You will learn how to activate caller ID, set up a Black List and protect yourself from fraudulent schemes. It is important to understand that the operation of the service depends on the relevance of the databases and timely updating of the application, so it is worth paying attention to the auto-update settings.
Before starting the procedure, make sure that the latest version of the application Yandex or a separate application Yandex with Aliceis installed on your device. Developers regularly improve spam detection algorithms, so older versions may not work correctly. Next, we will go step by step all the way from downloading to fine-tuning the blocking rules.
Installation and initial configuration of the application
The first step is to download the necessary software from the official store Google Play. It is recommended to use the official application Yandex with Aliceas it already has full blocker functionality built into it, which is synchronized with your account. After installation, run the app and log into your profile, if this did not happen automatically.
To activate protection, you must provide special permissions to the application. The system Android strictly controls access to calls and contacts, so blocking will not work without your explicit consent. Go to your phone settings, find the “Applications” section, select Yandex and open the “Permissions” item. Here you need to activate access to “Phone” and “Contacts”.
Inside the application itself, find the settings section, which is usually indicated by a gear icon or is located in the profile menu. Look for an item related to security or calls. This is where the switch is located, which is responsible for number identification and blocking unwanted calls. Activating this function starts the process of integrating the service into the system phone book.
⚠️ Attention: On some smartphone models (for example, Xiaomi or Huawei), the system may aggressively terminate background processes to save energy. You must add the application to the exclusion list or allow autostart, otherwise the spam database will not be updated on time.
☑️ Check before activation
Activation of caller ID and filtering
After granting permissions, the system will prompt you to enable the Caller ID function. This option allows you to check an incoming call against a huge database containing millions of numbers tagged by users. If a call comes from an organization with a bad reputation or a known scammer, a corresponding warning will appear on the screen.
For complete protection, it is not enough just to see the name of the caller, you need to automatically reject calls. In the blocker menu, activate the option "Block spam". Algorithms Yandex analyze call patterns: if a number makes hundreds of calls per minute, it is automatically marked as suspicious and included in the filter.
You can choose the level of filtering severity. Modes are available that block only confirmed spam, or more aggressive settings that cut off all numbers that are not in your phone book. The last option is effective, but may lead to missing important calls from couriers or doctors that you have not yet saved.
Enable the “Show organization name” option in the identifier settings. This will help you immediately understand who is calling: a bank, a delivery service or an advertising agency, even if the number is not saved in contacts.
Setting up black and white lists
Automatic filters are not always ideal, so manual list management remains a critical tool. Black list allows you to manually add a specific number that you want to block forever. This is convenient for annoying collectors or former partners from whom you do not want to hear a word.
On the contrary, White list serves as a guarantee that important subscribers will always get through to you. Even if the “Block all unknowns” mode is enabled, numbers from the white list will pass through the filter. Here it is worth adding contacts of close relatives, work and emergency services.
Lists are managed through the app interface or the system phone book. In the application Yandex go to the “Blocking” section and select the appropriate tab. Adding a number is done in one touch: just enter numbers or select a contact from the list.
- 📞 Black list: here are numbers whose calls will be dropped automatically without notification.
- ✅ White list: priority contacts that ignore any rules blocking.
- 🕒 Temporary blocking: the ability to mute all calls for a certain time (Do Not Disturb mode).
Integration with system dialing
To blocker worked as discreetly and efficiently as possible, it should be set as your default dialer app. In modern versions Android this allows you to intercept an incoming call before the phone starts ringing. If you are using a standard dialer, the integration may not be complete.
When setting up for the first time, the system may request confirmation of changing the calling application. Agree to this action by selecting Yandex as the main tool. Visually, the dialer interface will change: a service logo and additional buttons will appear for quickly blocking or adding a number to spam directly during a conversation.
If you prefer a native dialer from the smartphone manufacturer (for example, Samsung or Google Phone), a complete replacement may not be required. In this case, the blocker works in the background, using the access rights obtained earlier. However, the functionality may be limited: for example, the “This is spam” button may not be displayed on the incoming call screen.
Settings → Applications → Default selection → Phone application → Yandex⚠️ Attention: The settings menu interface may vary depending on the version.
Androidand manufacturer’s shells (MIUI, OneUI, ColorOS). If you do not find the “Call Application” item, use the search in the settings by entering the query “by default.”
Blocking SMS and instant messengers
Spam attacks not only through voice calls, but also through text messages. Advertising mailings from stores, banks and lotteries can clog up your inbox and distract you from important correspondence. The protection module Yandex can filter and SMS messageshiding them in a separate folder or deleting them permanently.
In the blocker settings, find section responsible for messages. Here you can enable keyword filtering. For example, if you do not participate in lotteries, add the words “winning”, “prize”, “promotion” to the stop list. All messages containing these phrases will be automatically marked as spam.
The function of blocking messages from numbers that are not in your contacts is also available. This is a radical measure that will completely protect you from advertising SMS, but can hide verification codes from services if you do not add them to the white list in advance. It is recommended to use a combined approach.
| Filtering type | Efficiency | Risk of missing important data |
|---|---|---|
| By spam base | High | Low |
| By keywords | Average | Average |
| Contacts only | Maximum | High |
| Manual blacklist | Spotted | Absent |
What to do if an important SMS ends up in spam?
Go to the “Spam” section inside the Yandex application or in the system folder unwanted messages. Find the email you need, open it and select the “This is not spam” option. The sender's number will be added to the exceptions, and the following messages will be sent to the inbox.
Reporting and updating databases
The effectiveness of the blocker directly depends on the relevance of the information. Databases Yandex are replenished in real time thanks to feedback from millions of users. When someone marks a number as “Fraud” or “Seller,” this information quickly becomes available to all other subscribers.
You can also contribute to overall security. If you receive a call from an unknown number and it turns out to be spam, do not just hang up the call, but click the “Complain” or “This is spam” button in the dialer interface. This action will send a signal to the server for analysis and subsequent blocking of this number for other people.
Regularly check for updates for the application in the store Google Play. Developers are constantly improving machine learning algorithms that identify new fraud schemes. An outdated version of the application may not recognize the new type of spam that is actively used at the moment.
The collective intelligence of users is the main driver of the effectiveness of the blocker. The more actively you mark spam, the clearer the broadcast becomes for all other subscribers.
